To a/ZZ whom t may concern:

Be it known that I, DRUEY T. KIRKPATEICK, a citizen of the UnitedStates, residing at Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in Vapor-Burners; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to improvements in vapor-burners; and it hasfor its object to provide a device for cooking or heating, in which oiland ,Water are united in a common vapor or gas and burned as a fuel.

The improvements will be fully understood from the following descriptionand claims, when taken in connection with the accompanying drawings, inwhich- Figure 1 is a vertical diametrical sectional view of my improvedburner, showing the construction and position of the respectivechambers; and Fig. 2 is a top plan view of the cap or cover.

Referring to the accompanying drawings by letter, A indicates myimproved water and oil vapor burner. This burner A consists of threeapartments or chambers, two for the reception of oil and water and theother for the reception of the gas or vapor generated therefrom.

B indicates the base chamber or apartment This chamber B, which isdesigned for the reception of coal-oil or crude mineral oil, is providedwith a concave bottom, it having been found that the same willfacilitate the feed of the air to the draft-tube presently to bedescribed. The chamber B, and likewise the other chambers, arepreferably cylindrical in form, and the Wall of the said chamber B isprovided in its upper inner edge with a recessed female threaded portionfor the reception of the succeeding upper chamber.

a indicates a threaded opening cut in the Wall of the chamber B toreceive a pipe, through which oil is fed to the said chamber.

C indicates the intermediate chamber or Y cylinder, which is designedfor the reception of the water. This chamber C, the bottom 5o of whichis ilat and has a recessed threaded portion to engage with the threadedportion of the Wall or chamber B, is provided at its top with a recessedfemale screw-threaded portion,similar to that of the chamber B, for thereception of the threaded portion of the top cylinder or chamber.

e indicates an annular opening, which is cut in the Wall of theintermediate or water chamber C. This opening e, the. Wall of which is6o threaded, is designed to receive a pipe or tube, through which thewater is fed to said chamber.

D indicates the top chamber, in which the generated vapor or gas fromthe water and oil is mingled. This chamber D is provided with a flatbottom portion, the outer edge of which is recessed and threaded toengage with the interior threads of the Wall of chamber O, and it isalso provided at the top of 7o the cylindrical wall with an interiorlyrecessed threaded portion to engage the threads of the cap portion ofthe burner.

E indicates the cap or top portion of my burner, the periphery of whichis provided with circumferential threads to engage the threads of topcylinder or chamber D, in the recess of which it is seated. This capportion is provided at diametricallyopposite points on its face aboutmidway between its 8o center and circumference with lugs or projectionsb, which serve to facilitate the unscrewing of the cap when it isdesired to remove the same.

At the center of the concave bottom of the cylinder B, I provide anannular opening, the Wall of which is threaded to receive a hollowthreaded nut or seat F. This nut F is provided with an opening throughits central portion, the lower portion of said opening 9a being largerthan the top portion, which is reduced, as shown, to facilitate thedraft or force of the air-induction. y

The Wall of the upper portion of the reduced opening is threaded, asshown, to ref ceive the threaded end of the air-conducting tube G, whichis preferably of the comparative diameter shown. This tube G,which eX-tends, as shown, almost to the base of the cap-nut of the burner, isintended to conduct a draft of air from below the bottom of the deviceto the burner-cap, where it forms a suction or draft in thegenerating-chamber of cylinder D, whereby the vapor of the water and oilin the successive lower chambers is drawn up thereto, and by reason ofthe current of air mingled and combined in a vapor of ahighly-combustible nature, whereby a bright clear light and heat of highdegree is furnished when the burner is ignited.

The bottom wall of chamber C is provided with a central annular opening,the wall of which is threaded to receive a connecting tube or sleeve H,which is exteriorly threaded to engage with the threads of the openingof said bottom wall. This tube H, which conducts the vapor or gas fromthe bottom cylinder or oil-chamber, extends up through the bottom wallof the generatingchamber a slight distance, said bottom plate beingprovided with a central annular opening of a diameter slightly greaterthan that of the tube H, whereby a communication is effected between thewater and generating chambers for the passage of the water-vapor. Thecapplate or top E is also provided with a central annular opening, thewall of which is threaded to receive a hollow nut F', which is providedwith exterior threads to engage the threads of the wall of the annularopening. This nut I1",.which is seated in the annular' opening of thecap-plate, is provided in the upper portion of the `wall of the annularopening with interior threads to receive the lower portion or section Iof the burner proper. This section I of the burner is shouldered, asillustrated, to form a shallow cylinder for the vapor when the burner isin operation. The depending body portion d of the burner-section I isprovided with a central annular opening of two diameters, the lowerportion being larger than the upper and provided at its top with arounded wall adapted to promote the draft.

At diametrically-opposite points in the wall of the cylinder portion ofthe burner-section I form minute perforations for the emission of theflame when in operation, of which there may be any desired number. Thewall of the burner-section is also provided at its top upon its exteriorsurface with a circumferential threaded portion to engage the threads ofthe cap portion of the burner.

J indicates the upper or cap section of the burner proper. Thiscap-section J is provided with a depending flanged wall, which isthreaded on its inner side to engage the threads of the lower sectionand secure it thereto. The cap of the burner proper is also provided inits central portion with a small annular opening for the emission offlame when in operation.

K indicates a depending flanged portion,

which forms the base or stand of my i mproved oil-burner. This stand K,which is preferably of a thickness similar to that of the wall ofchamber B, and which, if desired, may be formed integral therewith, isprovided in its periphery with numerous openings of the comparative sizeillustrated,

L indicates a plug, which is threaded onits exterior surface to engagethe lower threads of the wall ofannular opening in bottom of cylinder B.This plug L, which is designed for use when the device is not in use, isintended to stop the draft or circulation of air up through theVentilating-tube and thus prevent the evaporation of the oil and waterwhich is promoted by said draft.

In operation,when oil and water have been ,fed to their respectivecylinders or chambers, the plugL is removed and the burner placed upon astove or other heater to facilitate the primary evaporation of the oiland water. The forcible draft caused by concave bottom and reducedopening of the tube forms asuction and current of air in thegeneratingchamber, which promotes the evaporation of the water and oil,the vapor of which is thoroughly mixed by said current of air and fed tothe burner. After a short time the oil in the bottom of the burnerbecomes heated and boils the water in the chamber above, and the burn erproper-is thenignited and theburner removed from the heating agent, theevaporation being now facilitated by the heat from the burning vapor.

Having described my invention, what I claim is- 1. In a vapor-burner,substantially as described, the combination, with the mixingchamberhaving a top or cap and a burner connected therewith, of an oil-chamberand a water-chamber connected, respectively, with said mixing-chamber,and an air-induction tube leading from the bottom of the device to themixing-chamber, substantial] y as specified.

2. In a vapor-burner, substantially as described, the combination, withthe mixingchamber having a burner connected therewith, of awater-chamber and an oil-chamber arranged beneath the saidmixing-chamber, the threaded tube seated in the bottom wall of thewater-chamber and extending up into the mixing-chamber, and theair-induction tube leading from beneath the oil-chamber up through thethreaded connecting-tube to the mixing-chamber, substantially asdescribed.
